Laser

Laser (cekakan saka basa Inggris: Light Amplification by Stimulated Emission of Radiation) iku siji piranti sing migunakaké èfèk mekanika kuantum, pancaran kastimulasi, kanggo ngasilaké siji cahya sing kohèrens saka medium "lasing" sing dikontrol kamurnian, ukuran, lan wanguné. Sinar laser bisa sambung-sinambung lan kanthi amplituda-konstan (dikenal minangka CW utawa gelombang berkelanjutan), utawa detak, kanthi migunakaké tèknik Q-switching, modelocking, utawa gain-switching.

Jrpning operasi detak, akèh daya puncak sing luwih dhuwur bisa digayuh. Sawijining medium laser uga bisa duwé fungsi minangka amplifier optikal nalika di-seed nganggo cahya saka sumber liya. Signal sing dikuataké bisa mèmper banget karo signal input sajeroning istilah panjang gelombang, fase, lan polarisasi; Bab iki wigati sajeroning komunikasi optikal. Tembung kriya "lase" tegesé mroduksi cahya kohèrens, lan asalé saka tembung laser iki.
